Much has been written on the vacuum catastrophe and cosmological constant problem where we have the worst discrepancy between theory and measurement of about a factor of 120 orders of magnitude. In this paper, we improve this discrepancy by more than half which still remains very high, but also propose 3 avenues, one of which is an exciting prediction of a missing bosonic particle, that can help resolve the vacuum catastrophe. The paper builds on the standard theoretical calculation of the vacuum energy density using a quantum harmonic oscillator model and then sums the contributions of all the Standard Model's quantum fields vacuum states. The basis for this calculation is a new Zeta function regularization method used to tame the infinities present in the improper integrals of power functions. The paper also presents a few other findings in the area of vacuum energy.
